Description

[Detailed description of the invention] Industrial application field The present invention relates to a money acceptance control method for a vending machine.

(B) Conventional technology In general, when money is inserted into a vending machine, the amount of money inserted is returned when a customer requests the return of the inserted money, unless the user selects a purchased product. It looks like this. The amount of input coins can be returned as the input coin itself, which is held in the temporary storage unit after receiving it, as is often the case when processing banknotes and high-value coins. There are two ways to return the item in currency. However, in recent years, due to the rise in the price of automatically sold products, the acceptable range of input amounts has increased, and it has become impossible to pay out in the same type of currency that was inserted when returning the device.

Japanese Patent Application Laid-Open No. 57-209593 discloses that when 51 banknotes are inserted while one banknote is being held, if the banknote amount can be returned in a lower value currency, then 1 banknote will be returned. By holding a banknote and introducing the other banknote into the collection box, both of the banknotes will be accepted.If the customer requests the return of the inserted banknote in this state, the banknote will be returned and the banknote will be returned. Discloses that the amount of one banknote is paid out in low denomination currency. However, as the amount of money that can be accepted increases, the number of types of currency that can be accepted must also increase, and it is impossible due to space constraints to provide a coin storage section for each type of currency. If the amount can be paid out in a lower level currency, a method is adopted in which this amount is introduced into the payment box. However, when such an acceptance method is applied to the above-mentioned prior art, there are the following drawbacks.

For example, if the bill accepted by the banknote validator is 1,000 yen, and the type of currency introduced into the collection box is 500 yen coins, then if there are a predetermined number of 100 yen coins for change, 10 or more but less than 15, 100 yen coins are accepted. It is assumed that the change signal is output. If you insert two 1,000 yen bills now, a 100 yen change signal will be output, so one 1,000 yen bill will cost 1.
It is possible to dispense with 00 yen coins, and one coin is accepted and the other is held in a banknote validating machine. If a 500 yen coin is further inserted in this state, since a change signal is generated, the 500 yen coin is also accepted and introduced into the collection box. However, when the customer makes a return request in this state, the inserted amount of 2,500 yen is returned in the form of one thousand yen bill and 15 100 yen coins, but there is a shortage of 100 yen coins. At this time, the shortfall in 100 yen coins is paid out in 50 yen coins or 10 yen coins, which are lower-level coins, but if these coins run out of change, a situation may occur in which the input amount is not completely returned.

(/→ Problems to be Solved by the Invention As described above, according to the prior art, when deposited coins are directly introduced into the collection box, the amount of the coins is not guaranteed in some cases.

In view of the above points, the present invention provides an acceptance control system that determines whether the amount of a currency type to be directly introduced into a payment box can be guaranteed and determines whether to accept the currency type.

B) Means for Solving the Problems The present invention provides that when a plurality of money types can be inserted and a money type other than the one equipped with a corresponding dispensing device is inserted, the money type is directly inputted as direct input money. In the vending machine installed in the collection box, there is a means for detecting the number of coins that can be dispensed of a currency type other than the above-mentioned direct input currency type, a means for calculating the input amount by adding and counting the input currency amount, and a means for calculating the input amount from the input amount. sellability determining means for determining the possibility of selling a product at the selling price based on whether the required number of coins to be paid out in order to pay out the amount obtained by subtracting the amount is within the above-mentioned payoutable number; and a direct entry determining means that determines whether or not the direct entry currency can be paid out based on the number of coins obtained by subtracting . The possibility is determined, and the direct entry determining means is configured to determine the acceptance of direct entry currency for rOJ yen and all selling prices set in the vending machine.

(E) Effect With the above configuration, the total amount of the input amount actually input and the direct input currency amount assuming additional input can be refunded to a currency type other than the direct input currency, and the product can be purchased with this total amount. When the change can be paid out in a currency type other than direct deposit money even if the purchase is made, when the direct deposit money is actually inserted, it is guided to the collection box. Therefore, it is determined in advance whether the amount of directly received money can be guaranteed, and it is only accepted if it can be guaranteed.

(F) Embodiment Figure 2 shows a money processing mechanism that sorts input coins and distributes them to four appropriate channels depending on their suitability.In this example, ¥500, ¥100, ¥50, ¥ Each of the 10 coins is distributed. Coin slot (coin passageway (2) connected to coin slot (11)
) is equipped with a measurement sensor JsStsS that forms an oscillating magnetic field and measures the characteristics of the coin, such as its material, plate thickness, and outer diameter, based on the degree of influence caused by the passage of the coin. A genuine coin gate σ0 is arranged behind the coin passageway (2), and the genuine coin gate a6) appears from the board α depending on whether the selected coin is genuine or false, and transfers the coin to the genuine coin passageway (8). ) or the return aisle (9
).

That is, as shown in the side view of FIG. 3, a return passage (9) is formed between the outer cover (10) and the partition base, and
A genuine coin passage (8) is formed between the partition plate Ql) and the board QB, and when the drive solenoid a3 is not activated, the genuine coin gate αe protrudes to block the genuine coin passage (8) and return the coins. When the driving solenoid a is activated suddenly, the genuine coin gate is designed to introduce the coins into the genuine coin passage (8). Note that FIG. 1 shows a state with the outer cover Ql removed. A partition plate 0 is provided below the specie passageway (8), a first specie passageway (a) is provided between the partition plates aυ and au, and a second specie passageway (a) is provided between the partition plate αyu and the board α匈. They each form a specie passageway CI). Figure 4 shows the state with the partition plate aυ removed.
The figure shows a state with the partition plate section removed.

The coin gate circle is pivoted at one end and has a drive arm @ attached to the other end, and normally closes the first genuine coin passage (a), but when the drive solenoid Q4) operates, the drive arm @ is attached to the board. When it exits to the α side, it becomes in a state where the second specie passage Qυ is blocked.

In addition, the first specie passage (A) is branched into the first introduction passage (C) and the second introduction passage (goods) by the coin gate αυ, and the second specie passage eυ is divided into the coin gate αυ by the coin gate αυ. It is branched into a third introduction path (c) and a fourth introduction path (c). Coin gate a where a coin passage (27) is formed.
υ is configured to move in and out of a hole (to) drilled in the partition plate (11) by the operation of the drive solenoid Q5. In QFj, the coin passage slit (3) is connected to the fourth introduction path (
C), and at this time the second introduction path (goods) is blocked by the coin gate α.

In this state, the coins introduced into the first specie passageway roll horizontally and are introduced into the first introduction passage (c), and the coins introduced into the second specie passageway Qυ pass through the coin passing slit (5). It passes through and is introduced into the fourth introduction path (end). And drive solenoid α9
operates and the coin gate α~ exits, the coin passage slit @ exits to the board a3 side, the second introduction path (goods) is opened, and the fourth introduction path is blocked by the coin gate frame. . In this state, the coins introduced into the first specie passageway are directly introduced into the second specie passageway (goods), and the coins introduced into the first specie passageway are directly introduced into the second specie passageway (goods).
The coin introduced into the coin rolls laterally and is introduced into the third introduction path (c). In this way, by sorting after sorting, the specie passage (
The coins introduced into 8) are sorted into four ways depending on their type, and each of the ¥10 - ¥50 and ¥100 coins sorted into introduction path 124) (c) and (c) is a designated coin. ￥5 led to the pipe and distributed to the introduction path (c)
00 coins are led to the collection box. In other words, in this example, ¥
500 coins are considered direct currency. A coin dispensing device is installed below each coin pipe, ¥10/¥50＠¥
Each of the 100 coins can be paid out as needed,
¥500 coins cannot be dispensed O Figure 1 shows the control device according to the present invention in blocks, and the coin sorting device (to) has measurement sensors S, S!・The measurement signal from S8 is used to determine the appropriateness and type of the inserted coin, and the game is performed according to the determination result. In case of ￥10＠￥5o・￥100＠￥5゜O
A money signal a@b*csd is output in response to.

The input amount calculation device 01) calculates the input amount by adding and counting the input money amount upon generation of the money signal a*b@csd.

The input number counting unit # (to) has an input number counting unit for each coin type of ¥10, ¥50, and ¥100, and adds and counts the number of input coins of paddy in response to the coin signal aab*c. do. Each of the above-mentioned coin pipes corresponding to ¥10, ¥50, and ¥100 coins is equipped with a change detector that detects the presence or absence of change by checking whether a predetermined number or more of coins are stored in each of the coin pipes. The information output device CN outputs information on the effective number of change to be paid out for each coin type of ¥10, ¥50, and ¥100 depending on the presence or absence of out-of-change signals E, .E, and .Eto from the change detector. In this example, each change detector detects the presence or absence of change in each pipe based on 10 coins, and the change information output device 1C33 outputs information on the number of coins that can be paid out when an out-of-change signal is generated for that coin type. , "0" is output, and if the out-of-change signal is not generated, "1" is output as the valid payout number information D1.
0" is output. The sales price setting section (c) has a sales price set for each product type, and outputs sales price information. Payout number calculation device (Ir (goods) is ¥10, ¥50, ¥
A payout number storage unit M for each of the 100 coin types,
・M, ・Ml, and the number of coins inserted into the seed rice and the effective number of coins to be paid out as change are added and stored as the number of coins that can be paid out. Sellable judgment device @ (to) is input amount calculation bag *C3
The input amount information in 1) and the sales price information D in the sales price setting department (to)! The possibility of selling the product is determined by calculating the difference between the amount and determining whether this difference can be paid out with the number of payable coins stored by the payout number calculation unit # (goods).

Then, if the product can be sold, the device t (to) determines whether the product can be sold.
outputs a sellable signal for the product at that selling price,
As is already well known, a vending machine performs a vending operation by operating a product selection switch corresponding to the product in question. The direct entry determination unit @ determines whether or not direct entry coins can be accepted when the sale availability signal is generated in the sale availability determination device t (g), and in this example, the acceptance of 500 yen coins is determined. Normally, a ¥500 rejection signal is output to the direct entry determination unit 0x1 coin sorting device (to), and when this signal is input, the coin sorting device (to) determines whether the input coin is a proper ¥500 coin or not. Even coins can be returned. In other words, the coin sorting device (to) is ¥5
Even if a 00 coin is identified, the genuine coin gate frame is held in a state protruding from the board a2 and the return passage (9
). In addition, when determining whether the product can be sold, the sellability determination device (to) outputs information on the number of coins that must actually be paid out at the time of sale of this product to the payout number calculation device It (34)k, and the calculation device (goods) This number is subtracted from the number of stored sheets and stored. The direct entry determination unit Gη generates a sellable signal, and after determining that it is sellable, the payout number calculating unit (
It is configured to determine whether the amount based on the number of sheets stored by the company (goods) is 500 yen or more, and if it is 500 yen or more, the output is stopped due to the prohibition of receiving 500 yen messages.

Acceptance of ¥SOO coins is based on the assumption that an additional ¥500 coin has been inserted while the input amount has been calculated in the input amount calculating device Nυ, and the total amount of ¥500 assumed to be additionally inserted and the actual input amount is The determination is made based on whether either of the following two conditions is satisfied. In other words, ■ The total amount can be paid out in a coin type with a ¥500 mark, and ■ When a product is purchased with this total amount, change can be paid out in a coin type with a ¥500 mark. There are two ways to do this. ■The condition is for additional input of ¥
This determines the possibility of returning the amount invested including 500 yen, and when a product worth 0 yen is purchased, the change will be 500 yen.
Determination is made based on whether it is possible to pay out with a coin type less than or equal to the following.

As described above, according to the present invention, it is determined whether the difference between the input amount and the product selling price can be paid out based on the number of change that can be dispensed in the vending machine. If possible, subtract the number of change that must be paid out for the sale of the product from the number of coins that can be paid out, and if the amount calculated by the number of coins that can be paid out after subtraction is 500 yen or more, it is determined that 500 yen coins can be accepted. It is. Then, the present invention makes such a determination for all selling prices and rOJ yen set in the vending machine, and if it is possible to accept a 500 yen coin in all cases, it is determined to accept a 500 yen coin.

More specific operations will be explained with reference to the flowchart in FIG. Currently there are 12 ¥100 coins in the ¥100 coin pipe.
First, we will discuss whether or not two 100 yen coins are inserted in a state where coins are stored, and it is possible to accept another 500 yen coin.

In this case, 200 yen is calculated in the input amount calculation device c11), and 100 yen is calculated in the input amount calculation device (b).
Input sheet number counting section M1. "2" is counted.

In step 31, the sales availability determination device t subtracts the selling price from the input amount of the input amount calculation device ll01) to calculate the amount of change when a sales operation occurs. Calculation is performed when is set to "0" yen. Therefore, the sellable determination device @(to) sets 200 yen as the calculated amount.

In step S2, the payout number calculation device 04) calculates payout valid number of coins information from the change information output bag eaa.

The number of coins that can be paid out is calculated from the input number information Ds from the input number calculation bag e (to). In this case, the change detector on the ¥100 coin pipe will output a change out signal E. is not output, and the change information output bag *Oa is 1 in the valid payout quantity information D1.
Outputting 0 sheets. Therefore, the payout number calculating device (b) calculates 12 coins as the payable number of ¥100 coins, and stores the payout number storage unit M. Store in. In addition, the payout number calculating device 1c34) calculates the payable number of coins for ¥50 and ¥lO coins in the same way, but ¥50 coins and ¥
None of the 10 coins were inserted, and the out-of-change signal E.
-E, the valid payout number information outputted from the change information output device 1 (to) according to the presence or absence of change information output device 1 is stored as is in the payout number storage units M1 and Mll as the payout possible number.

In step S3, the sellability determination device (to) stores the calculated amount of 200 yen in the payout number storage units M1, M, and Ml.

It is determined whether or not the payout is possible based on the respective payoutable numbers of ¥10, ¥50, and ¥100 stored in .

In other words, the sellability determination device li1@ is ¥100 from the calculated amount.
- ¥50 and ¥10 are subtracted within the range of payoutable coins with priority given to the high amount, and when the subtraction amount becomes rOJ yen, it is determined that it can be sold. In this example, it is determined that the sales price is "0" yen, and the input amount is 200 yen, and the number of coins that can be paid out is 12 yen.
It allows for refunds since it can be paid out from a single ticket.

If it is determined to be sellable, in step S4, the sellability determining device (G) outputs the payout required number information D4 determined in the sellability determination process to the payout number calculating device 04. In this example, two 100 yen coins are the required number of coins to be paid out, and the payout number calculation device 1C34 subtracts two coins from the stored number of coins in the payout number storage unit Mt@ to store 10 coins.

In step 85, the direct entry determination unit @ determines the number of payable coins stored in the payout number calculation device 1c14) for ¥50.
Determine whether 0 can be paid out. In this example, ¥100 is 10
Since it is possible to pay out up to 500 yen coins, it is determined that 500 yen can be paid out, and in step S6, it is possible to accept 500 yen coins for "0" yen. In other words, with the current amount invested, an additional ¥5
Even if 000 coins are inserted, it is determined that this total amount can be returned in coins other than 500 yen coins.

In step S7, the direct entry determination unit 0η determines whether it has been decided to accept 500 yen coins for the 01 yen and all - selling price routes.

Then, the process returns to step 81, and the bag #(c) is determined to be salable.
The first selling price of the selling price setting unit (2) is subtracted from the input amount of the input amount calculating device Gυ. For example, if the selling price of the first item is 150 yen, the sellability determination device i! (c) sets 50 yen as the amount of change.

In step S2, the payout number storage unit (il) calculates each payoutable number of coins from ¥100 to ¥50Φ¥10 and stores them in the payout number storage units M10@M, , Ml.

As mentioned above, the number of ¥100 coins that can be paid out is 12, but for ¥50, assuming that 10 or more ¥50 coins are stored in the corresponding coin pipe, the payout number storage unit MsK is Store 10 pieces.

In step S3, the sellable bag Wt (to) determines whether the calculated amount of 50 yen can be paid out based on the number of payable coins stored in the payout number calculation device (b). In this example, it is possible to pay out the calculated amount from the payoutable number of 50 yen, and it is determined that it is possible to sell at a selling price of 150 yen.

In step S4, the sellability determination device (c) subtracts 1 from the stored number of coins in the payout number storage unit M, so the payout number calculation device c34).

In step S5, direct entry determination unit C3? ) is the number of payable coins stored in the payout number calculating device i1 (b).
It is determined whether ¥500 can be paid out. In other words, if an additional 500 yen coin is inserted with the current amount of input, even if a product worth 150 yen is purchased with this total amount, it is determined whether change can be paid out in a coin other than 500 yen coins. Toki ¥1
Since it is possible to pay out up to 112 pieces of the old 0, ¥500 can be paid out, and in step S6, ¥50 is paid out for the selling price of 150 yen.
Decide to accept 0 coins.

Then, in step S7, the direct entry determination unit Gη is “O”.
It is determined whether it has been decided to accept ¥500 coins for yen and all sales prices.

Repeat the above process to obtain ¥5 for all sales prices from 1st to nth according to the sales volume type of vending machine.
When it is determined that the 00 coin is accepted, the process moves from step S7 to step S8. In step S8, it is determined whether it has been decided to accept 500 yen coins for "0" yen and all selling prices, and if all are accepted, in step S9 a 500 yen acceptance prohibition signal e is sent to the coin sorting device (to). Stop output.

Therefore, when the coin sorter rIt (to) determines that the coin is a 500 yen coin, it moves the genuine coin gate tilt out of the board a3 and guides it to the genuine coin passage (8).
Further, the coin gate aη is moved by the operation of the driving ring I to receive a 500 yen coin into the money receiving box.

When accepting ¥500 coins, insert ¥5 into the amount calculation device 6υ.
When 00 is added, the process starts again from step S1, but at this time, 700 yen has been calculated in the input amount calculation device #6υ.

In the process from step S1, it is determined whether "0" yen is accepted for the input amount of 700 yen and 500 yen coins are accepted at all selling prices. In this case as well, the number of ¥100 coins that can be paid out is 12, and the number of ¥100 coins that can be paid out is 7.
Since 00 yen can be paid out in 100 yen coins, it is determined that the coins can be sold, and 5 coins are stored in the payout number storage unit M1o by subtracting the required number 7 to be paid out from the required number 12 that can be paid out. Then, when it comes to step S5 as a result of the judgment that it is possible to sell, the direct entry judgment unit 07) stores in the payout number storage unit M1゜, and it is possible to pay out ¥500 with the number of payable pieces stored in the payout number storage unit M1゜.
Decide to accept ¥500 coins for “0” yen.

Next, the possibility of selling is determined for all sales prices from the first to the nth, and if the sale is possible, the possibility of paying out 500 yen is determined. For example, if the selling price is 150 yen, the sellability determination device (to) sets 550 yen as the calculated amount. The number of ¥100 coins that can be paid out is 12, and up to 10 ¥50 coins can be paid out with change, so it is determined that 550 yen can be paid out and this product can be sold.
The payout number storage unit M to K is the required number of payout pieces 12
The required number of coins to be paid out is subtracted from 5, and 7 coins are stored therein, and the required number of coins to be paid out, 1, is subtracted from the required number of coins that can be paid out, 10, and 9 coins are stored in the payout number storage unit M. And the direct judgment part 0 in the judgment that it is possible to sell? ) determines the possibility of paying out ¥500, but in this case, it is possible to pay out ¥500 with the payout number stored in the payout number storage unit M1゜, so for a selling price of 150 yen, ¥500 coins will be paid out. Decide on acceptance.

If we decide to accept 500 yen coins for other sales prices in the same process, direct entry determination unit C1? ) continues for ¥5
Stop outputting the 00 acceptance prohibition signal e.

Therefore, even if the next 500 yen coin is inserted, the coin sorter (t) will introduce it into the collection box.

When this second ¥500 coin is accepted, the input amount calculation system f! When 1200 yen is calculated for 10υ, the determination process begins, and the sellability determining device @051 first determines whether rOJ yen is sellable. In this case, since 1200 yen can be paid out with 12 pieces of 100 yen coins, it is determined that it can be sold, and the required number of pieces that can be paid out is 12 pieces in the payout number storage units M and o.
Subtract the number of coins required to be paid out, 12, from the number and store "0" coins.

Then, if it is determined that it can be sold, the direct admission judgment department (37) will be charged ¥50.
The possibility of a payout of 0 is determined, but in this case, the stored number of coins in the payout number storage section is "0", so it cannot be paid out, and the
It is decided that 500 yen coins will not be accepted for 0'' yen.

Then, the possibility of sale is determined for all sales prices from the first to the nth, and if the sale is possible, the possibility of paying out 500 yen is determined. Even if it is determined through this determination operation that ¥500 can be paid out for all sales prices, it is not possible to pay out ``0'' yen, so in step S9, the direct entry determination unit Gη sends a ¥500 acceptance prohibition signal e.
is output to the coin sorting device (to). Therefore, when the third ¥500 coin is inserted into the coin sorting system @(to),
Since only the second 100 yen coin can be paid out at the time of return, when the insertion of the third 500 yen coin is detected, the genuine coin gate Qe is projected from the board a2 and guided to the return path (9).

In this example, if the ¥500 coin cannot be paid out within the payable number of ¥100 coins, the ¥500 coin will not be accepted.
¥50 and ¥10 for the amount insufficient to pay out with 100 coins.
It may be possible to accept 500 yen coins as long as they can be paid out within the number of coins that can be paid out.

As described above, in the present invention, when the amount is calculated in the input amount calculation bag [C31], the next directly input coin is ¥50.
This is to determine in advance whether or not to accept the input of 0. And this judgment is an input amount calculation bag lol
Whether the total amount of the input amount of r01) and ¥500 can be paid out in a coin type less than ¥500, and when the product is purchased with this total amount, change can be paid out in a coin type less than ¥500. This is done based on whether it can be paid out. ¥50050
A vending machine into which zero coins, for example, 1,000 yen bills, can be inserted is equipped with a banknote recognition device, so that once a banknote is inserted, the banknote can be returned at any time until the product sales operation begins. Therefore, when a thousand yen bill is inserted and 1,000 yen is calculated in the input amount calculation bag man, if 10 or more 100 yen coins (but less than 14 coins) are prepared in the coin pipe, 50 yen or more (but less than 14 coins) are prepared. If you have all 10 change coins, you can sell them all at a selling price of 1,000 yen or less. In this state
If 500 yen is inserted, the 1,000 yen banknote held in the banknote recognition device can be returned when the machine is returned, so it can be dealt with by dispensing 5 100 yen coins, but when paying out change, 1,000 yen banknotes are accepted from the sales item. You must pay out in ¥100 coins, and depending on the selling price, you may not be able to pay out change. However, in the present invention, when a thousand yen bill is inserted and it is determined whether a product with a selling price of 200 yen can be sold, for example, ¥
The number of coins that can be paid out for a 100 coin is 2 by subtracting 8 from 10, so the number of coins that can be paid out for a 500 yen coin is 5 yen.
The payout of 00 is determined to be impossible. Therefore, the acceptance of 500 yen coins can be prohibited, and the above-mentioned problem can be prevented.

(G) Effects of the Invention According to the present invention, if direct deposit money is further inputted in the current state of the input amount, the total amount can be returned in money other than the direct deposit money, and even if the product is purchased. Control is performed so that when direct deposit money is inserted, it is accepted only when change can be paid out in money other than direct deposit money.

Therefore, when directly received money is accepted, it can be guaranteed. Moreover, since the acceptance of directly deposited coins is determined using the sales availability determination process when there is an input amount, the determination process is not only easy but also reliable.
